Purpose
This study assessed the results of two-portal knee arthroscopic synovectomy in terms of bleeding recurrence, knee function, quality of life (QOL), and radiographic staging in a prospective case series of patients with haemophilia.
Methods
Nine knees from eight patients (median age 16.1 years; range 9.6–25 years) with haemophilia and recurrent knee haemarthrosis were prospectively evaluated. Yearly recurrence of bleeding was evaluated once a year for 5 years postoperatively. Range of motion (ROM) and radiographic staging, as well as results of the short form (SF)-36 and subjective knee form of the International Knee Documentation Committee (IKDC) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaires, were evaluated before surgery and at the end of follow-up.
Results
Mean bleeding recurrence was significantly reduced during the 5-year follow-up period. Questionnaire results showed significant improvements (IKDC P = 0.015, WOMAC P = 0.011, and SF-36 P = 0.023), whereas ROM was not significantly affected. Arthropathy progressed from Arnold–Hilgartner radiographic stage III to stage IV ( P = 0.0082).
Conclusions
Two-portal knee arthroscopic synovectomy was effective at reducing bleeding recurrence and improving knee function and QOL in patients with haemophilia, but did not interrupt the progression of radiographic changes.
